Flow Control Valve 2FRE10-4X/10QK4M - Bosch Rexroth R900963211

A controlled feed loses accuracy as soon as flow drifts with load pressure. The 2FRE10-4X/10QK4M is a pilot-operated flow control valve that follows the command value signal up to 10 l/min and keeps doing so up to 315 bar operating pressure.

Benefits

• Up to 10 l/min with electrical adjustment, the command value comes from the controller instead of a hand spindle.
• 315 bar maximum operating pressure in size 10.
• Flow direction A to B across 2 ports and 2 switching positions.
• Subplate mounting to ISO 6263-06-04-0-13, the valve sits on the manifold without a pipe run.
• 24 VDC through a connector, 3-pole (2 + PE) to EN 175301-803, external electronics drive the adjustment.
• NBR seals for HL hydraulic fluid at 6.7 kg.

Applications

The valve suits axes whose speed the controller sets and corrects, such as feeds on machine tools or approach movements in presses. The narrow band up to 10 l/min fits slow travel that needs fine resolution. Ramps and characteristic curve are matched to the machine cycle through the external electronics.

Manufacturer

Bosch Rexroth, material number R900963211. The valve runs on HL hydraulic fluid with NBR seals, which belongs in the check when the oil grade is chosen.
